MACHINE FOR PAoKiNe ENSILAGE, an.

SPECIFICATION forming part of Letters Patent No. 296.863, dated Aprill5, 1884. Application tiled February 2S, 1884. (No model.)

To @ZZ whom, it may concern,.-

Be it known that I, Louis MGMURRAY, of the city and county of Baltimoreand State of Maryland, have invented a certain new and usefullil'achinefor Packing Ensilage, Src.; and I do hereby declare that thefollowing specification, taken in connection with the drawings furnishedand forming a part of the same, is a clear, true, and completedescription of my invention.

My said machine embodies a supporting or carrying roller which operatesafter themanner of a garden-roller for compressing, and aseries ofvertically-reciprocating stamps which are lifted and dropped during themovement of the machine, so that on causing said machine to be movedover and upon a mass of ensilage within a silo the stamps will cooperatewith the roller by olosely'stamping the ensilage. i

In the machine as illustrated the stamps are operated by means of ahand-crank, and with the operator standing on and moving with themachine; but the hand-crank may be also turned by the operator whilewalking beside the machine. I have also so organized said machine thaton turning said crank for operating the stamps the machine is alsopropelled; but without applying power to said crank one or more of thestamps can be lifted and dropped by merely trundling the machine. I havealso so organized said machine that its operator can cause the machineto travel forward or backward while operating the stamps; but, ifdesired, the stamps can be arranged to be oper-k ated only while themachine is moving forward or backward, or without moving it in eitherdirection.

After a full description of a machine embodying my invention, the novelfeatures will be specified in the several claims hereunto annexed. Y

To more particularly describe my invention, I will refer to theaccompanying drawings, lin which Figure I is a side elevation of amachine embodying the several features of my invention. Figs. 2 and3 arerespectively a plan view and a front elevation of said machine. Fig. lis aV vertical longitudinal section of the same on line i, Fig. 2.

The frame A may be of wood or metal, and is varied in its constructionaccording to the compressing-roller.

particular arrangement of the mechanism. As here shown, the frame iscomposed of two end pieces, each composed of a sill, a, two verticalstandards, a', land a top, c2, andthese end pieces are joined at theirfront ends by transverse upper and lower bars or beams, a3 a4, and arear platform, a, connects their rear ends. On each sill c there is araised bearingblock, a, for the main supporting-axle, and at the rear ofthe frame a goose-neck, a, serves as a bearing for a pivotedguide-wheel. The lower front cross-beam, a?, is elevated above the topof the sills a by means of interposed blocks, and the several parts ofthe frame are firmly bolted together.

However my machine may be organized, it must have the supporting-axle B,which is also the compressing roller axle, there being mounted thereonand keyed thereto, side by side, several pulleys, b, which make upthe Insome cases the peripheries of the supporting-wheels orcompressing-roller are roughened or scored, instead of being smooth, asshown. The guidewheel c has abroad, fiat face, is mounted in apyokepivoted in a bearing in the gooseneck a', and to its pivot there isfastened a hand-wheel, c', notched at its periphery, so that saidguidewheel may be readily turned in any direction and locked in positionby a spring-pawl, c2. Eyebolts in the sills, near both ends thereof,enable the attachment of a team whenever desired.

The stamps D may be varied in number; but as here shown there are four,each having a straight helve, d, fitted to slide in verticalguidebearings provided therefor in the two front cross-beams, c3 and at.Each helve is provided with a hole, d, and with a pin, d2, looselysecured by a strap or chain to the up.- per cross-beam, c3, so that whensaid stamps are fully elevated they can be supported .by the pins-as,for instance, when the machine is to be moved from place to place. Thestamps are lifted and dropped by means o f a series of tappetarins, e,on the shaft f, which is coupled to a hand-crank shaft, g, by means of alarge-gear, f', and a pinion, g. The crankshaft extends across themachine, has suitable bearings at each end, and is bent between thebearings to afford a long hand-bar, g2, so that IOO the crank may beturned by one or two men standing on the platform a5, or by operatingthe end crank, g3, which can be operated by a man walking beside themachine. Each stamphelvevhas a curved-face tappet-lug, e', with whicheach set of the tappet-arms e successively enga-ge as they revolve, thuslifting the stamps and permitting them to drop. The number oftappet-arms in each set may be varied according to particularrequirements; but I have found that four will serve a good purpose.rllhe tappet-lugs c are adjustably mounted on the helves, so that byvarying their vertical position the height of lift may be varied, andthus vary the stamping force of the machine.

As thus far described, it will be seen that' however the machine may bemade to move on vits wheels-z'. c., whether .pulled along by hand or bya horse-the stamps can "be operated by the hand-crank and the stampingblows delivered regularly and progressively upon whatever surface themachine may be caused to pass over. It is, however, desirable that theaction of the stamps should be always proportioned to the speed at whichthe machine is trundled, and therefore I have or- `ganizedpropelling-gearing, which is also operated by the hand-crank. VAs seenin-Fig. l, thetappet-arm shaft j has at one end the large gear f and atthe other end the small gear f2, and that this latter engages with thegear b on the main supporting-axle B by way of two intermediate gears,b2 and b3, so that when the crank-shaft f/ is rotated for operating thestamps the machine will also be propelled forwardly, or so that when thestamps are held 'up by their pins the machine will be propelled. As thusorganized, it will be seen that if a team be attached and the machinedragged slowly forward the stamps will be lifted and dragged, even ifpower be not applied to the handcrank, especially if the surface withwhich the supporting wheels or roller is in bearing-contact is one whichwill afford a suf- I cient degree of friction with the periphery of thesupporting-roller to thus cause one or more of the stamps to beoperated. The stamps, as shown, are provided with vertically-slidinghelves, so as to enable the machine to be compactly built; but in caseswhere compactnessis of little consequence the stamps may be in the formof hammers with pivoted helves and operated by tappet-arms, like thewell-known fulling-stocks in fulling-mills. The weight of the stampsshould be varied according to circumstances; but I find that about fiftypounds in the stamp-shoes is ample for good results, with a fall of fromten to twelve inches.

W'hen the machine is constructed to operate the stamps only during itsforward movement,

the gears b3 and b4 are mounted on Xed studs, and when the machine is tobe moved rearwardly the stamps are first fully elevated and confined, soas to not interfere with the tappet-arms during their backward rotation;but if the gear b be mounted upon a movable arm, h, as shown, then thetappet arm-shaft may be stationary during the rearward movement of themachine,when the latter is to be pulled along instead of being propelledby power applied to the crank; but if said gears be not disconnected,and vthe stamps be so elevated as to not interfere with the backwardrotation of the tappet-arms, the machine can be moved rearwardly bybackwardly rotating the crankshaft. v

Then the machine is constructed so as to have the stamps operated whilethe machine moves rearwardly, the movable arm h is provided with a studon which another gear, b", is mounted, so that after throwing gears b2and b apart and meshing gears b4L and b the forward rotation of thecrank-shaft will not only properly operate the stamps, but also causethe machine to travel rearwardly. The movable arm h and its gears serveas a reversing gearclutch, and it is provided with a lever, h', having athu nib-latch, h2, which engages firmly with a stationary perforatedsegment, h3, so as to enable said arm to be locked in either of itsthree positions of adjustment.

It is obviously desirable that during the traveling movement of themachine the stamps should be only in brief contact with the suryface tobe stampedfand therefore I arrange the tappet-arms so that they willcommence to lift the stamps practically simultaneously, or at leastwithvery slight intervals, and employ as many arms in each set (i. e, foreach stamp,)

` as will allow the stamps to briefly occupy their lowest position.

Whenever it is desired to operate the stamps for awhile in any one spot,the shifting-clutch is so set that the machine will remain stationary onits wheels or roller; and if it be desirableto drive the machine ineither direction, so as to operate as a compressing-roller without thestamps, the latter are fully elevated, and power is then applied to thecrank-shaft.

In .the machine organized as shown the stamps and the roller co-operateas compressing devices-i. e., when the machine is movingA forward, theroller evens the surface previously'stamped by the stamps, and when themachine is movingbackwardlythe stamps have a well-condensed surface onwhich to operate, it being vobvious that in both cases the twocompressing devices co-operate in performing the service intended; andit will be specially obvious, if the power for operating the stamps bederived, in whole or in part, from the supporting-axle while the machineis being moved to and fro, that the roller will then constitute anessential element in the stamp-operating mechanism 5 but in this casethe stamps would not generally be so heavy as when the handcrank isemployed.

It is to be understood that I do not preclude myself from such obviouschanges in the proportions of the several gears as will best enable IOOthe stamps to be readily operated by power derived by Way of thesnpportingaxle, in lieu of by the way ofthe hand-crank.

My machine, if used solely as an ensilagepacker, will be obviously inservice only a short time during each year; but it should be observedthat it is practically capable of use in other connections-21s, forinstance, it may be profitably employed after the manner of road-pavingmachines as heretofore organized, for surfacing carriage Ways and Walks,and especially in connection with broken stone, as the stamps willoperate effectually in embedding and even crushing small stones. Themachine can obviously also be employed in breaking and crushinglimestone, shell, or gypsum, whether for roads or fertilizers, and forcrushing roots, dsc. it being only necessary to provide a suitableplatform for the stamps to Work upon and to discopnect thesupporting-axle from the tappet-arm shaft.

Having thus described myinvention, I cla-im as new and desire to secureby Letters Patentl. The combination, substantially as hereinbeforedescribed, of the frame mounted upon a rotating supporting-axle, theverticallyreciprocating stamps, the tappet-arm shaft,- the hand-crank,and gearing for connecting the hand-crank to the tappet-arm shaft and tothe 3o rotating supporting;-axle,whereby the machine 4:. The combinationof the frame mountedupon a rotating axle, one or moreverticallyreciprocating stamps, a tappet-arm shaft for op erating saidstamps, reversible clutch-gearing for connecting and disconnecting saidshaft and supporting-axle, and a handcranl, substantially as described,whereby the machine can be propelled in either direction bythe handcrankwith o r without simultaneously operating the stamps, or the stampsoperated Without propelling the machine, as set forth.
